• Narrow layouts stack cards; oversized overlays scale to fit the selected monitor without cropping.
• GPU/CPU readings are grouped and ordered by meaning.
• Hardware headings display detected models, with shortened names where recognized.
• Default layout restores the reference metric set; switching layout modes can retain selected metrics.
• Telemetry graphs display historical values, units, timestamps and crosshairs at the hovered position.
• Numeric fields, sliders and dropdowns require keyboard focus before mouse-wheel input changes their values.
• Dark Mode moved to Settings → General → Appearance.
• Fresh settings default to Dark Mode; existing saved choices are preserved.
• Improved alignment of Settings component groups and controls.
• Updated application, assembly, executable and updater metadata to 2.0.5.

V/F Curve Editing

• Edits, offsets, flattening, locks and graph reset remain pending until Apply.
• Closing the V/F editor discards unapplied edits.
• Ctrl+Z restores the previous draft or exact previous applied state.
• Repeated Undo follows the change history instead of returning every change to stock.
• Switching curves or sections preserves drafts and Undo history.
• A point drag counts as one Undo step.
• Flatten operates independently without changing a voltage cap or lock.
• Reset graph stages the entire default curve.
• Main-page Reset also resets core and independent-domain curves.
• Native Undo work runs away from the UI thread.

Fixed

OSD and Telemetry

• Improved label, value and unit alignment, compact layouts and connector-table reflow.
• GPU OSD history resets when PCI bus identity changes, including identical-name adapters without a UUID.
• Paused, unavailable or stale CPU/frame readings no longer appear current.
• Frame plots preserve missing-data gaps.
• Frame statistics reset when the tracked process or swap chain changes.

Tuning and Recovery

• Improved V/F X-axis visibility in Dark Mode.
• Curve Apply and Undo use the main tuning transaction and recovery checks.
• Failed Undo readback requires a verified reload before another Apply.
• Main Reset clears open and cached curve drafts and history.
• Invalid MSVDD drafts remain visible through telemetry updates instead of being silently replaced.
• Added restore-first migration checks for older saved Direct records.
• XBAR/SYS voltage-demand errors retain the underlying NVIDIA failure and observations captured before recovery.

Windows Startup

• Correctly quoted executable paths, matching working directories and the expected startup argument are accepted while preserving task ownership and rollback checks.
• Automatic error reports include bounded startup launch fields, including failures inside wrapped exceptions.

Removed

• Set offset and Set + Lock buttons.
• Separate Target frequency field and Unlock point button.
• Separate Target / Set target controls in independent-domain curve editing.
• Flatten + cap behavior.
• Automatic live V/F writes while editing and when closing the editor.
• Header Dark Mode button.
• Previous stock OSD as the fresh-install default. Existing Custom canvas layouts and widget styles remain supported.

Compatibility Notes

• Existing settings, profiles and recovery records retain their established storage locations.
• RTX 30-series firmware extension remains power-only, requiring matching GPU, firmware and native TGP bounds.
• Direct CPU package watts remain unavailable on AMD family 1Ah unless a compatible sensor provider supplies the reading.
• Unsupported metrics display an em dash.
• RTX 5060 Ti XBAR/SYS diagnostics improved; a functional fix on that card remains unverified.
• Startup quoting passed software checks; the original affected PC’s exact task-save failure remains unconfirmed.
• FPS statistics measure application presentation intervals.
• The desktop OSD supports windowed and borderless applications. True exclusive fullscreen remains unsupported.
• Native operations without complete inverse records retain their existing Reset/Restore boundaries.

2.0.4

Added

• Customizable OSD with colored readings and load, power and fan bars.

• Removed unused Space Grotesk and IBM Plex Mono font resources from the release.

Notes

• Existing settings, profiles and recovery records carry over.
• RTX 40-series firmware extension remains power only.
• MSVDD remains unavailable for unsupported linked-equation firmware; the interface explains the reason.
• Native changes without complete undo records still use their own Reset/Restore controls.
• Recovery reacts to observed failures; it cannot guarantee rescue from a completely frozen GPU or Windows session.

2.0.3

• Improved recovery after sleep and driver reconnection.
• GPU Reset preserves telemetry history and maximum readings.
• Reset telemetry remains the dedicated action for clearing graphs, recorded maximums and pin warning history.
• Kept Revert, Reset GPU settings and Reset telemetry as separate actions.

Telemetry and per-pin monitoring

• Improved telemetry layout when opening, resizing or moving between displays.
• Preserved connector maximums through temporary missing readings and connector visibility changes.
• Kept maximum histories separate by GPU and sensor source.
• Current pin readings turn red at the configured warning threshold.
• Peak readings retain their red warning after current falls. Changing the threshold re-evaluates their color without erasing the recorded maximum.
• Added A to current and maximum pin readings, with three decimal places.
• Restored the TOTAL POWER: and TOTAL MAX POWER: labels.
• Improved layout for monitoring both connectors.

Editors, profiles and benchmarking

• Added a standalone, configurable OSD with text, bars, graphs, per-pin layouts and import/export.
